What makes it "worse" is if they fail to accomplish their goals.They managed to accomplish some of their goals with the Holocaust, which makes it more "efficient" than American Slavery.

But they failed to teach the Blacks what's what with the slavery. At first it was good and worked well, they picked their cotton etc, but look at the blacks of today, they don't know their place.Today we have Kanye west and the likes chimping it up even in public media, blacks all over Europe raping people etc.

Thus, the American Slavery was worse in efficiency. Just subpar methods really, they gave them too much freedom for each year, were too lenient.

What happened in Ancient Greece has less impact on our society today than for example the American Slavery, which everyone can see the results of these days.

Slavery exists today in some countries. Now. Is that worse than Civil War era slavery due to its' presence in time?

Reason Alex chose "The American Slavery" and "The Holocaust" is due to the american blacks and the jews being the most vocal groups regarding these two incidents these days. They have not forgotten what happened to this day.

People still remember the slavery in america and the holocaust and what it did for their families etc.

The slaves that exist today in some countries you speak of have not been able to let themselves get heard / nobody seems to care, even though it is happening as we speak.

Nobody cares today either what happened in Ancient Greece / Egypt regarding slavery since it is so long time ago and forgotten by most.No brit/irishman holds a grudge against the Scandinavians for what Vikings did back in the day.

The american indians were almost wiped out, then placed in confined areas

The jewish extermination during lenin and stalins day was as bad as hitlers

The crusaders wiped out zillions of muslims if they wouldn't convert (ever wonder where their hatred stems from)

In ghenghis khans day the equivalent of whole countries was wiped out at a time

The romans would kill, enslave, make slaves fight for them, and also toy with them in public entertainment

Shit, there's more!

every nation on planet has done this. This is standard protocol for warfare-+ but to add to your list; Mao Tse tung confiscated the food Chinese aboriginal tribes people resulting in 30 million (some say way more) deaths by famine.

Hideki Tojo (Responsible for 5,000,000 deaths) want to talk about ruthless, no one beats this man, not Hitler not Stalin, No one. This guy had a facility that would experiment with the most extreme torture methods possible and conducted experiences with weapons, chemicals and the works. Over a quarter million people went through that facility.

all experiments were for purpose of knowing how much a human can endure and weak spots and biological review on all levels, field test of the worst imaginable were conducted on human.Experiments included;

Freezing a human to deathburning a human to deathSkinning a human to deathbreaking bones to deathstarve to deathpartial amputations, partial freezing with liquid nitrogen on certain bodyparts, partial burning, smoke inhalation of various chemicals, sleep deprivation.

You name it, this guy did it. This is the king of all who have no remorse, the devil himself.

Then there is Pol Pot, took out 20% of Cambodia, another heartless who was obsessed with ethnic cleansing. Murder and Famine were the norm for him but often people died from over working 100 hours of labor per weeks. This guy is know for certain massacre of several hundred people where they were taken to dig their own grave and then where beaten with bars to death. Some got buried alive and others where shared even a more brutal and gruesome death.

Tojo is responsible for Pearl Harbour and drawing the USA to WWII

I did not know of these experiments, only of war crimes.Did he do this on his own people, on chinese, or prisioners of war ?

That went both ways, the Ottoman Turks were not to be fucked with at their peak.

Otherwise, as for the OP's original question, I'd say it depends how you look at it. Blacks, for the most part were bought, so they had real "value" to the owner, and while they were not always treated good, for the most part they were kept alive. The Jews were "free bodies" coming from conquered lands, so the Germans treated them as disposable. So, I guess it comes down to, which is worse, a lifetime of being treated like shit, or a regular life, followed by a horrible last few years. Personally, I'd say the Jews had it worse. As a black, you always had the chance to have good hair/light skin and be a house negro.
